About this tool

Enter the deposit, the APY, the term in months and your tax rate. The calculator shows the interest earned, the interest after tax and the value at maturity. APY already includes compounding, so it is applied directly.

How a CD earns

A certificate of deposit holds your money for a fixed term at a fixed APY. The interest over a term of m months is the deposit times (1 + APY) to the power m/12, minus one. Interest is taxable income in the year it is credited, even if you do not withdraw it.

Example

$10,000 at 4.25 percent APY for 12 months earns $425, or about $331 after a 22 percent tax rate.

Tips

Bank CDs are insured by the FDIC up to $250,000 per depositor per bank. Early withdrawal usually costs several months of interest.

計算示例

Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.

獲得最佳結果的提示

在相信結果之前先檢查每一個輸入項，因為一個錯誤的數字就會改變整個答案。請使用工資單、賬單、證書或合同上的準確數字，並記下計算日期。稅率、門檻和規則會不時變化，因此對於稅費和法律事務，請將結果視為估算，並與本頁註明的官方來源核對。您可以嘗試任意多個方案；不會儲存或傳送任何內容，重新整理頁面會清空輸入。
